SAWlNG-'MAVCYHINE No. 824,009. llieciflcation of Letters Patent.Patented June 19, 1906.

Application tied April 29; 1,995. Serial No. 258,102.

To tu @hom it may concern: o engages e series of holes o* in thesections Be it! known that we, SIMON Jonnsross Giur-'and- JoHN HonNiNo,citizens of the United States, residing at Oakland inthe county ofAlameda and State of California, have invented a new and useful Imrovement in SawingMachines, of which t e following is a specicaton.

The object of the invention is to provide a` novel machine of theendless-saw type adapted forcutting in any position-cit er vertically,horizontally, or at any desiredangle.

further object isY to rovide means for cutting at any height desired,whereby trees may be out near or far from the ground and lar e or smalllogs sawed with equal facility.

he invention consists in the above and certain other novel features ofconstruction and in combination of parts, more fully and particularlydescribed hereinafter and pointed out in the claims.

Referring to the accompanyin drawings, Figure 1 is a perspective view omy invention, showing it in position for sawing a log. Fig. 2 is aperspective view of the device as arranged for sawin down a tree wi th asquare horizontal cut. of the same in position for making an obli ue uward cut. Fig. 4 is a detail of the sii eb ock and pulley. Fig. 5 is atransverse vertical section thereof. Fig. 6 is a erspective view of aportion of the saw, an Fig. 7 is a plan view of the saine.

Our invention comprises in the present embodinient bed-plates A and A',supporting standards B and B for carrying the pulleys around whichtravels the endless saw D. The bed-plate A. comprises sills E, connectedat either end by cross-bars F F', provided with undercut grooves G, inwhich move correspondingly-draped ton ues H of slide-bars I.Alongitudinal bar Vconnects the inner ends of the slide-bars I', andbraces Kv are provided to secure: the

roper degree of rigidity between the slide- Ears andY longitudinal ber.Braces LV 'extend obliqixely from the outer ends of fthe cross-bars F toa meeting-point M, and a cross-piece N at a suitable distance frein themeeting-point forms a trian lar opening in Awhich is stepped an extensile bar O, conn' prising two sectionsc and o', vheld in sliding contactwith each other by sleeves o. A pm Fig. 3 is a perspective view.

thns retanin the bar in the desired state oi extension. uy-ropes o,attached to eyebolts j ata suitable distance on either side of thecenter of the bar J, extend diagonally inward to a ring o, attached tothe end of a rope o, passing through ane ebolt o, attached to the end ofthe extensible bar O and having connected to its free end a suitableweight o. Allin e on the front end of the longitudinal bar aving one ofits leaves provided with a ratchet-face, carries the `smandarci-supportb, having a. rounded lower end and provided with a washer 7', having aratchet-face to coact with the ratchet-face of the leaf and connected tosaid leaf by a bolt j and mit Y The ine ination of the standard-'supportmaybe varied by loosening the nut thus allowing the coastingratchet-faces to sli by each other until the desired degree ofinclination is'attained, after which the nut is tightened, thusretaining the support in the desired osition.

Col ars b', b', and b, attached vto the standard-support Zi, retain insliding contact therewith t e standard B, and extensible braces b5, comrising sections b and bl, sliding upon cachot 'er through eyes bs on theen aging ends o the section and secured in t e adisted position bthumb-screws b", extend ein ears b on t e central collar t to bolts t onthe longitudinal bar J and the slide bar I.' A pin b, en aging holes b"in the standard and standard-su port', serves to retain the standard atthe dpesired elevation.

The standard B, in siiding contact with thc support b and embraced bythe collars t', 5*,

Yand t comprises two sections t" and b, connested byariction-hinge1;,having a pivotpin if* with a screw-threaded end, upon Vwhich is a nutb for the purpose of increasing the friction between the leaves of thehinge when desired.

An undercut groove t in the rear face of the standard B receives acorrepondinglyshaped tongue 'Bof a slide I, ig. 5, provided on'its reeface with bearings i to receive a 'cross-pin if, having rigid therewitha stud-shaft i, on which is journaled a grooved ulley C, retained on.the shaft by a pin e. llhe ends i. ofthe cross-pin i are screwthreaded,and nuts i* engage with the screwthreaded ends for the purpose of fixingthe stud-shaft to the bearings. Eyebolts 1.", secured to the slides I,are engaged by ropes t assing over pulleys i", on the upper and Powerends, respectively, of the standard for the purpose of raising andlowering the slides and retaining them at the proper elevation.

A collar` b, slidingly mounted in the up er section b of the standard Band provi ed with ears b2", gives attachment for extensible races b,similar to the braces b, and connected at their lower ends to bolts b onthe slide-bar I and the bar J, respectively. A bar 23, engagin staplesb, on the upper' and lower section o the standard B, serves to retainthe sections in alinement.

The bedlate A comprises sills F and a longitudinalconnecting-bar J',provided with a hinge for securing the standard B thereto. The standardB is a duplicate of the standard B and carries a pulley C', similar tothe pulley C, but having secured to its free face a powerwheel derivingmotion from a source .of power (not shown) throu h an endless rope Y.

Extending over the pleys C C and in the grooves thereof is an endlesssaw D, composed of links d, wedge-shaped in cross-section and havingteeth on the wider edge. A hole d pierces each end of the link, and theends are shaped on the arc of a circle having the hole as its center.One end of the link is formed into a tongue dz and in the other end is agroove to receive the tongue of the succeedlng link, and a rivet securesthe sections together. The ton ue dz is flattened and reduced within thecircumference of the circle on which the ends are shaped to accuratelyreceive the lips of the grooves, thus foaming a rule-joint.

To cut down and afterward saw u a tree, we place the bed-plates oneither si e of the tree and turn the upper sections of the standardsupon their hinges until the saw is at the proper angle, retaining thesections in position Vby props under their free ends. The slides aremoved to their roper positions,the pulleys are lined up and ocked to theslides, and power is imparted to the saw. When the tree is felled, thebed-plates are placed on each side of the trunk the section of thestandards are alined and fixed, and the saine rocedure is repeated withthe slides and puleys. The saw receives its feed in the first instancethrough the moving of the slides toward the tree and 'in the second. bythe Weight of the slides and saw.

It will be evident that by constructing our apparatus in two detachedportions we secure many important advantages, among which may bementioned ease of transportation, adjustability to topographicalconditions, andcheapness of construction. An efficient tensioning of thesaw is also obtained by this feature, and as a consequence a gain inefliciency with no increase m power. The provision of a. link-saw is `animportant part of our invent1on,since by its use the utilization of all.the advantages of our detached construction is made possible, the hihest degree of flexibility between the detae ed portion being thusobtained.

The provision of the hinge j permits the inward inclination of thestandard-supports withrespect to the bed-plates.

The saw forms no part of the present application, the same forming apart of ourcogrinding application, filed July 20, 1905, Serial Thesliding frame, comprising the slide-bars I and the bar J, to ether withthe flexible cord 07 and the weig t o", forms an efficienttensioning'means for the saw, and the tension may be varied byincreasing or decreasing the size of the weight.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is
